/*iterator*/() requires std::default_initializable<OuterIter> && std::default_initializable<InnerIter> = default; | (1) | (since C++20)
constexpr /*iterator*/( Parent& parent, OuterIter outer ); | (2) | (since C++20)
constexpr /*iterator*/( /*iterator*/<!Const> i ) requires Const && std::convertible_to<ranges::iterator_t<V>, OuterIter> && std::convertible_to<ranges::iterator_t<InnerRng>, InnerIter>; | (3) | (since C++20)

Constructs an iterator.

1) Default constructor. Value-initializes the underlying iterators, and initializes the pointer to parent ranges::join_view with nullptr.
2) Initializes the underlying `outer_` iterator with std::move(outer), and the pointer to parent `parent_` with std::addressof(parent); then calls `satisfy()`.
3) Converts /*iterator*/<false> to /*iterator*/<true>. Move constructs the underlying iterators `outer_` with std::move(i.outer_), `inner_` with std::move(i.inner_), and underlying pointer to parent `parent_` with i.parent_.

### Parameters

parent | - | a (possibly const-qualified) ranges::join_view
outer | - | an iterator into (possibly const-qualified) ranges::iterator_t<Base>
i | - | an /*iterator*/<false>
